There are a few places where faults can develop for the wiper motor circuit. Agreed, start with the fuse - it is #6 in the main fuse panel. The switch could well be faulty or have dirty contacts, but it is a fiddly job to open up and clean. I suggest first you check if you have 12V across the KLG and BLG wires going to the wiper motor when the ignition is on and the switch in the normal wiping position (regular speed wipe).
The small grey connector plug at the motor can develop bad contacts - worth checking and cleaning that.
In the motor itself, the carbon brushes could be worn and no longer making contact with the armature. Also, the park switch could have corroded contacts and be dropping voltage.. The motor magnets could have come loose (they are only glued on from the factory). Or you could have a fault with the motor windings.
I suggest that, if you have voltage going to the motor but it is not turning, remove the motor and have an electric motor repair shop test it for you. I am sure there will be plenty of such specialists in Accra. They should be able to diagnose a fault with it, such as burnt windings or simply worn brushes and repair for you for a reasonable price.
If you don't have voltage at the motor, but the fuse is good, then it would indeed point to a switch fault.
that relay is for the Interval function of the wiper motor, the lowest position of the switch. it is blue in color and is mounted above the Cruise Control box in a Left Hand Drive car passenger side. You need to remove the cruise control box first to see it.
what might be wrong with that relay, can I possibly see a photo of that relay so I can find it easy
Here is the Series 2 wiper relay. According to SNG Barratt it is NLA. Branded "SELECO" who I think are a Spanish electrical manufacturer.
The reason I have this relay is to try and replicate its fitment to the Series 1 wiring loom, so I can have the luxury of a "single wipe" function, maybe by installing a push-button on the dashboard.
But the series 2 wiring diagram is less than helpful to say the least. Maybe the McLean diagrams will assist.
So, I have been trying to graft the wires together from the wiring harness that was chopped and diced from the old S2 car I dismantled.
A bit of a nightmare. Now I know how the Iranians felt when trying to paste together the shredded documents from the ransacked US Embassy!
Sorry, I'm not much help with the subject wiper problem, but often I cannot help myself!
PS, by the way, I also had no idea what this relay looked like when trying to locate it.
Fortunately, my dear wife came to the rescue.
She has the uncanny knack I finding anything in my Spare Parts Department (back shed), based on my vague descriptions, even though she knows nothing about cars.
Just amazing.
The fuse is in the main fuse panel by the driver's legs. When you open the fuse box cover, there should be a sticker on the back of it showing which fuse is which.
The relay is on the auxiliary fuse panel board on the passenger side. On my Series III, the relay does not look like the one in the earlier posting, but instead is a blue plastic casing, same size and shape as a normal relay.

Thanks Andy,
My worry was locating the relay, for the fuses area at times is my playground so I know there 😀😂

Please confirm if the wipper relay is the one hiding on top there as in the attached pictures
That relay is only in use when you choose the intermittant wipe function. I don't think your problem lies there if the wipers are not working in normal or fast wipe mode.
Here is a page from the wiring diagram showing how the wiper circuit is configured:

The relay has power on only the Redgreen wire and rest tested and has no power.
Now the issue is locating the wipper motor to check that too

Thanks AndyPlease where do I locate the wipper motor?
